It's not clear what, exactly, you want to do but the WizFi210 is an inexpensive WiFi-to-Serial adapter that can do both infrastructure (connect to LAN) or ad hoc (connect peer-to-peer with your laptop). It is SMD so you might want to look, instead, at the ConnectOne Nano Socket iWiFi or Mini Socket iWiFi which cost about twice as much but are simpler to handle as far as mounting. All are rather simple to work with, offering modem-like AT commands for control. The ConnectOne modules have additional interfaces (SPI, USB for both & Parallel for the nano) and also have more built-in protocols like email and network time and have SSL3 security.
